Application for these Goodyear Polyglas 14 x 7 F70-14

[ELEFUNTMAN]

Early 70 roadrunner maybe? I was told the early ones didn't have the size in white letters on them, later cars did.

Ya Bill I hear ya. Maybe they needed to move that type of tire. I actually like the look of the wide treads better.

The Polyglas no size versions had been available from the middle of '68 when the Cobra Jet Mustangs came onto the market. The Polyglas tire also showed up in '68 on the Hurst/Olds that year (G70-14 white stripes)..

The elevated size version of the Polyglas started to show up in October of '69. It was a rolling change as they could not supply molds to all of the plants at the same time. By the end of December all of the tires on the new cars were the elevated size.

The Speedway Wide Tread is correct tire for the Chevelle and Camaro in '69, same as in '68. Pontiac, Oldsmobile, Buick had all moved their orders for Goodyear to Polyglas. Ford was wearing Polyglas for their performance tire. Mopar was wearing Polyglas as well. AMC too.

As Speedway Wide Treads being used to the end of '69.... We have some information available that the Polyglas was available on the Chevy order sheets for Chevelle and Camaro from 2nd quarter '69. There have also been one owner cars that have been documented wearing Polyglas from the factory. I do not have a single piece of paper showing the change but as stated, all of the other car makers were using Polyglas. That means that the ONLY two car lines using F70-14 Speedway Wide Treads were Chevelle and Camaro. I believe that it was Goodyear making the decision to stop making the F70-14 Speedway Wide Tread and move production to Polyglas. I do not mean to upset anyone, but I believe that enough evidence is out there to support the Polyglas usage from the April '69 timeline moving forward.

If anyone has documents to prove this otherwise, I would love to see these. If anyone wants to discuss this, please feel free to call me. Again, I am happy to help and sell want you want to put on your car. My cell is 816-654-3400.

For Mopar:

For 1969 only the Road Runner and Super Bee Spring Specials had the option of RWL FGB tires. You could get either Redline or WSW FGB tires as an option in 1969 though. Hemi cars came standard with FGB tires (15" Redline with WSW a NC option) as did the A12 440+6 Road Runner and Super Bee (G70x15 FGB Redlines only).

Mopar started offerring RWL FGB tires as standard and optional tires on 1970 models.

The Corvettes never wore Polyglas .. the wore Speedway Wide Tread F70-15’s from ‘68-‘72.

I am not saying this is the only one.... you just asked for proof, which I gave you documentation from GM that they were available starting 2Q of ‘69. I also gave you pictures... These came from a respected member of the Camaro community... contact me with further questions.

I think any tire vendor that tells a buyer this is the correct tire for their 69 Chevy is doing their customer a dis-service because it is most likely not the tire used on their car. Just sell them the tire that was on 99.999999999999% of the cars.

Agreed.
